Paper Abstract

In this study, we have demonstrated that a single foveal lesion can produce suppression of central cone function and increased sensitivity of parafoveal receptor systems that might be adjacent cones, partially functional long wavelength cones, or normally suppressed rods. Passive and active movement of receptors during the repair process and damage to the neural retinal represent additional sources of spectral sensitivity modulation that may explain some of the complexities of change observed in the post-exposure measurement period. These retinal sensitivity changes may provide a retinal basis for earlier behavioral investigations of punctate foveal damage where enhancement effects were observed.
